There is a recent and interesting post on MO: erdos-harary-tuttes-dimension-of-graph-progress-in-last-48-yrs that I know a friend of mine can answer. I had in mind to let him know via this feature:

Know someone who can answer? Share a link to this question via email, Google+, Twitter, or Facebook.

Then I realized that this box is not available for the questions that already have at least one answer. In other words, it seems that it is only available for the questions with no answer. Am I right? Of course, I can e-mail my friend independently. But, I cannot see the reason behind such distinction. Is there any reason? If not, I suggest to have that box for all questions.

    $\begingroup$ Are you aware of 'share' that seems to provide a similar functionality and stays present? Since you did not mention it, I could imagine you are not and might find it suffcient, but also that your are but still want this, hence the question. $\endgroup$

  • $\begingroup$ @quid Yes, I was aware of "share". But it seems that it has a rather different functionality. To be honest, I personally am more curious than in need of that box. If a question has it, why another hasn't. $\endgroup$ Commented Aug 30, 2013 at 19:30
  • $\begingroup$ Related post on meta.SE: Under what conditions is a user invited to “share a link to this question”? This came up in connection with this recent post: Why do we link to Twitter, Facebook or Google+ below every question? $\endgroup$ Commented Jan 10, 2017 at 1:01

As quid remarked, the share button below the post has exactly the same functionality.

    $\begingroup$ Sorry, at least in my situation the functionality is not exact. g+, f, and twitter are all filtered where I live, but e-mail is not. And for that reason, the box under unanswered questions works for me, but the share button does not so. $\endgroup$ Commented Aug 30, 2013 at 20:06

    $\begingroup$ @Amir: That's what the url box is for. All the email link does is launch your program to compose emails and start an email with the link in the body. If you really need a button for email in the share box then post a clear and specific feature request here or on meta.so. $\endgroup$ Commented Aug 30, 2013 at 20:17

    $\begingroup$ One might also mention that there are plenty of people who don't use G+, Facebook or Twitter (I stand before you as an example), but it's a safe bet that anyone who uses MO also uses email. $\endgroup$ Commented Aug 30, 2013 at 20:49
